Abstract: The cooler weighs over a kilogram (1093grams) and comes with two 130mm
fans arranged in a push-pull configuation that scale from 2100-to-1200RPM.
Behind all the unncessary fan shroud is an aluminum fin tower split down the middle.

In this review Frostytech will be
testing a promising looking heatsink from Thermaltake called the FrioOCK. However you pronounce
the name, the Thermaltake FrioOCK is a 162mm tall variation on the familiar tower heatsink
with a lot of potential.

The cooler weighs over a kilogram (1093grams) and comes
with two 130mm fans arranged in a push-pull configuration that scale from
2100-to-1200RPM. Behind all the bulky fan shroud is an aluminum fin tower
split down the middle and connected to a thick copper
base plate by six 6mm diameter sintered metal wick copper heatpipes. The FrioOCK is compatible
with the complete range of current Intel and AMD processors and is rated to heat loads
of up to 240 Watts!

As you might expect by its appearance, the Thermaltake
FrioOCK heatsink has a footprint of 143x136mm so it's
best suited to full size computer cases. The cooler ships with two
130mm fans that drive up to 121CFM of air, so
it can be a bit loud running at full speed. The
fans are non-PWM so the manufacturer attaches a manual fan speed controller to manage
speed if quieter operation is desired. Retail price is around $75.

The interesting bits of the Thermaltake FrioOCK heatsink are hidden behind the plastic fan shroud - each nickel plated aluminum fin is split down the middle, forming two cooling towers. The six
6mm diameter heatpipes are all aligned along the outer edge of the fins where airflow
from the twin 130mm fans is strongest.

In most
other respects the Thermaltake FrioOCK
is a pretty typical tower heatsink. As an added measure to ensure low thermal
joint resistance, the heatpipes are soldered to each of the aluminum fins and to the copper
base plate.

Heatsink Installation Hardware

Thermaltake's FrioOCK heatsink ships with separate brackets for
Intel socket LGA775/1155/1156/1366 and AMD socket AM2/AM3/FM1 processors. Each set
of brackets is screwed onto the base of the
heatsink and threads through the motherboard
with a rear support plate. Unfortunately this requires access to the rear of the motherboard to fasten a
set of nuts, making any future CPU swapping a major maneuver.

Given that this heatsink
weighs 1093 grams, the solution that Thermaltake chose does assures that it
won't be going anywhere.

FrostyTech's Test Methodologies are outlined in detail here if you care to know what equipment is
used, and the parameters under which the tests are conducted. Now let's move
forward and take a closer look at this heatsink, its acoustic characteristics,
and of course its performance in the thermal tests!
